Composite ship hybrid power system based on ammonia-hydrogen driving

Abstract

The invention aims to provide a composite ship hybrid power system based on ammonia-hydrogen driving. The systemcomprises a liquid ammonia supply device, an ammonia fuel power device, a hydrogen fuel power device, a ship main bus and a gearbox, a liquid ammonia tank is connected with an electric heater, the electric heater is connected with the ship main bus, the electric heater is connected with an ammonia fuel engine, te ammonia fuel engine is connected with a reversible motor, and the reversible motor is connected with the gearbox and the ship main bus; the hydrogen tank is connected with a proton exchange membrane fuel cell, the compressed air is connected with a proton exchange membrane fuel cell, and the proton exchange membrane fuel cell, a first inverter and a second circuit breaker are sequentially connected and connected with the ship main bus; the ship main bus is connected with a main motor through a main motor switch, the main motor is connected with the gearbox through a main clutch, and the gearbox is connected with ship propellers. The problems of excessive emission of sulfur dioxide and hydrocarbon, low waste heat utilization rate and the like when the current ship sails can be solved.

Description

technical field [0001] The invention relates to a ship power device, in particular to a ship hybrid power device. Background technique [0002] With the increasingly stringent maritime discharge regulations, the issue of ship pollutant discharge has attracted more and more attention from the shipping departments of various countries. Moreover, the continuous development of global trade also puts forward higher requirements for the carrying capacity of ships. Although the traditional diesel engine propulsion method can quickly meet the load demand of the ship during navigation, it has disadvantages such as low energy utilization rate, excessive fuel consumption and excessive noise during operation. Although electric propulsion has the advantages of cleanliness, fast response, and high operating efficiency, it has disadvantages such as poor battery life, frequent switching of working conditions, easy damage to the ship's power grid, and high operation and maintenance costs. ...
